ACT Premium 2007 asking for License Data

I have ACT Premium 2007 running on a terminal server for several remote users in different offices. Everything was working until this morning. One of the remote offices with 3 users are now getting an inquiry when opening up ACT. The program is asking for the License data as if this was a new product. I cannot get it to take me to the page to enter our license data.

The other 3 remote offices are not getting this inquiry. Any help on why this occurred and how to correct it would be appreciated.
